J/ψ PRODUCTION IN A GLAUBER MONTE CARLO FRAMEWORK

Abstract

By means of a Glauber Monte Carlo framework, the J/ψ production at RHIC energies is studied with the EKS98, EPS09 and HKN07 shadowing parameters. With a χ2 analysis of the experimental data given by PHENIX, a significant dependence of the absorption cross-section, σ abs , on the J/ψ-nucleon center-of-mass energy, [Formula: see text], is revealed with the HKN07 shadowing, but an unconspicuous dependence is shown with the EKS98 and EPS09 shadowing. In this paper, the nuclear modification factor Rd Au vs y, pT and N coll are also calculated and the theoretical results are in good agreement with the experimental data.
